           a = a.replace("'", "~");
           alert(a);
       }

i需要输出~~~



但只有第一个字符正在替换..并且输出〜''

i need an output ~~~

but only first character is replacing..and getting output ~''

推荐答案

尝试：

Try:

function ReplaceCharacter() { 
var a = "''";
a = a.replace(/'/g, "~");//g is global match flag to replace all the occurance. 
alert(a);
}

尝试如下...

Try like below...

a = a.replace(/'/g, "~");

像这样修改你的函数，

Modify your function like this,

function a() {

           var a = "\'\'\'";
           a = a.replace(/'/g, "~");
           alert(a);

       }
